The difference between mitochondria isolated from young and aged mice. (A), the membrane potential was assayed by JC-1 method. (B), mitochondria redox ability was measured as the ratio of fluorescence intensity (a.u./mL) to mitochondrial suspension concentration (μg/mL). (C), mitochondrial swelling test. Young mitochondria mean mitochondria from young mice, and aged mitochondria indicate mitochondria from old mice. Mito, mitochondria. *p < 0.05, **p < 0.01 compared with the young mito. Student's t test was employed to compare the difference between the young and aged mito groups.
